Note:Contact an authorized dealer for lowvoltage battery access, testing orreplacement.
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the low voltage battery negativepost. This can cause inaccuratemeasurements of the battery conditionand potential incorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect the low voltage battery performanceand durability. This may also affect theperformance of other electrical systems inthe vehicle.
For longer, trouble-free operation, keep thetop of the battery clean and dry.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings aremaintained by power from the low-voltagebattery. Some engine computer settings,like the idle trim and fuel trim strategy,optimize the driveability and performanceof the engine. The clock and radio stationpresets are also maintained in memory bypower from the low-voltage battery. Thesesettings are erased when a techniciandisconnects and connects the low-voltagebattery.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 317). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 83).Reset the radio station presets. SeeAudio System (page 317).
6.Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km)to completely relearn the idle trim andfuel trim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fueltrim strategy.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
If storing your vehicle for more than 30days without recharging the battery, werecommend that you disconnect thebattery cables to maintain battery chargefor quick starting.
